This paper presents a method for managing and modeling a product family as a configurable product. The method enables efficient management of a large number of product variants. The modeling is based on a recently proposed conceptualization of configuration domain, which is a synthesis and extension of the main approaches to configuration. The concepts of the conceptualization are components, a...

The present work overviews the application of recommender systems in various financial domains. The relevant literature is investigated based on two directions. First, a domain-based categorization is discussed focusing on those recommendation problems, where the existing literature is significant. Second, the application of various recommendation algorithms and data mining techniques is summar...

Massive results from researching and developing technologies have been piling diversely such as patent, paper, or news article. To improve the technological competitiveness, most companies have tried to analyze the results efficiently. The amount of the accumulated results is extremely large, so we have difficult to analyze them. But we have to analyze the big data containing the results of dev...

This article proposes an empirical test of whether aggregate economic behavior maps from the real to the virtual. Transaction data from a large commercial virtual world – the first such data set provided to outside researchers – is used to calculate metrics for production, consumption and money supply based on real-world definitions. Movements in these metrics over time were examined for consis...

Digital archivists and traditional digital forensics practitioners have significant points of convergence as well as notable differences between their work. This paper provides an overviewof howdigital archivists use digital forensics tools and techniques to approach their work, comparing and contrasting archival with traditional computer forensics. Archives encounter a wide range of digital ma...

Risk is one of the main features of modern societies. With the Internet a new media has appeared, which on the one hand has increased the risk associated with information: free accessibility, interactivity, globality, and connectivity of personal, economical, political and media communication have all led to a loss of journalistic control over the information market. On the other hand Internet-...

We study generalized inverses on semigroups by means of Green’s relations. We first define the notion of inverse along an element and study its properties. Then we show that the classical generalized inverses (group inverse, Drazin inverse and Moore-Penrose inverse) belong to this class. There exist many specific generalized inverses in the literature, such as the group inverse, the Moore-Penro...

Although product development research often focuses on activities prior to product launch, for long-lived, adaptable products like software, development can continue over the entire product life cycle. For managers of these products a challenge is to predict when and how much the products will change, and to understand how their development decisions influence the timing and magnitude of future...
